It accepts bits from 1\/16 inch up to 1\/2 inch capacity, making it suitable for a wide range of drilling applications across metal, wood, and composite materials. The chuck uses a ball bearing design for smooth, consistent tightening without a key. The steel construction delivers the durability required in production or jobsite environments. Sleeve diameter measures 40 millimeters, and closed length is approximately 3.27 inches, with an open length of approximately 2.99 inches. Licensed machinists, millwrights, and skilled tradespeople are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis chuck is well suited for residential and commercial trade applications where quick bit changes are a priority. The 3\/8-24 threaded mount is a common spindle thread found on many corded and cordless drill platforms. It is appropriate for use in light manufacturing, maintenance and repair operations, HVAC equipment assembly, electrical panel fabrication setups, and general mechanical service work. The keyless design reduces downtime when cycling through multiple bit sizes on the job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKeyless operation allows fast bit changes without a chuck key\u003c\/li\u003e\n  \u003cli\u003eCapacity range of 1\/16 inch to 1\/2 inch covers standard drill bit sizes\u003c\/li\u003e\n  \u003cli\u003eBall bearing design provides smooth chuck actuation and consistent gripping force\u003c\/li\u003e\n  \u003cli\u003e3\/8-24 threaded mount fits a wide range of drill spindles\u003c\/li\u003e\n  \u003cli\u003eSteel chuck body for durability in trade and production environments\u003c\/li\u003e\n  \u003cli\u003e40-millimeter sleeve diameter for a secure grip during tightening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct threaded replacement chuck for drills and drill presses with a 3\/8-24 spindle thread.

Disconnect or de-energize the drill or drill press before removing or installing the chuck. Thread the chuck clockwise onto the spindle until fully seated, and use the appropriate spindle lock or arbor block to secure the spindle while tightening. Do not overtighten using impact methods, as this may damage the spindle threads or chuck body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Capacity\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Capacity\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey Type\u003c\/strong\u003e: Keyless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSleeve Diameter\u003c\/strong\u003e: 40 millimeters (approximately 1.57 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClosed Length\u003c\/strong\u003e: 83 millimeters (approximately 3.27 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 76 millimeters (approximately 2.99 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.23 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CKS1309020MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754063561010,"sku":"CKS1309020MSC","price":143.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29303aca5204431cb82658556759a5b6.jpg?v=1788943227","url":"https:\/\/voomisupply.com\/products\/accupro-cks1309020msc-keyless-drill-chuck-1-2-in-threaded-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
